Scientific American Letter to the Editors: “Brain Trust” A Rare Success Against Alzheimer’s, March 2017.

“Brain Trust” in the March issue left me with 2 questions. 1. there is no proof that less cortical surface are resulted from poverty vs. that poverty is the result of smaller cortical surface area in parents that then genetically pass this problem along to their offspring (genetic factors are common most psychiatric disorders); and 2. There is no evidence that food and/or educational/ tutoring vouchers would perform worse than the giving these families cash. Clearly some cash subsidies will be diverted.
